Markets are focused on monetary policy decisions from the U.S. Federal Reserve and Bank of England (BoE) this week along with key UK inflation data, as investors bet on an end to their interest rate hiking cycles.
Money markets see an 80% chance of the BoE hiking rates by 25 basis points to 5.5%.
The domestic annual inflation rate, due on Wednesday, is expected to show a rise to 7% in August from 6.8% in July, while core inflation, which excludes energy and food, is forecast to slow to 6.8% from 6.9%, according to economists polled by Reuters.
"We expect the BoE to hike, but it's a close call. Even if the BoE hikes, it is likely to be the last hike of this cycle," said Mohit Kumar, chief financial economist Europe at Jefferies, in a note.
Shares in Kingfisher sank 12.2% to the bottom of the benchmark index as the B&Q owner downgraded its annual profit forecast by 7% following lower sales in France and Poland.
British online supermarket Ocado Retail, a 50/50 joint venture between Ocado Group and Marks & Spencer, maintained its full-year outlook as it reported a step-up in third-quarter revenue growth.
Shares in Ocado gained 1.6%.
Meanwhile, the Organisation for Economic Co-operation and Development (OECD) cut the UK's growth forecast, now expecting the economy to expand 0.8% in 2024 from 1.0% projected earlier.
